i had a car like that too. the GSL-SE efi and intake bolt right on, and it really works well!

the only thing that doesn't work between the gsl-se intake and S4 engine are the air injection passages, so it'll never pass smog. the S5 engine goes back to the same air injection port that mazda used on everything else, so it will pass smog.
